Brief Quote / Description of Testimony

H blood group substances detected, fully consistent with victim, if she was a secretor, which could not be determined, and also with Criner. The analyst testified that 44% of the population are O secretors and could have been the donor. If the victim was a secretor, however, the H substances could have originated solely from her. See Part II.A.1 for a description of the problem of masking and non-quantification and discussion of similar cases. Hairs compared excluded defendant.

Examples of Non-Public or Corroborated Facts and Inconsistencies

Quotes from testimony #3

Quotes regarding any deal or leniency with informant, or prior use of informant

● No, but recanted in Frontline interview ● The one witness who testified told journalists years later that both he and his wife had made clear to the police that Criner was at work stacking logs when the crime occurred. It was “physically impossible” for Criner to have committed the crime. He was never asked about this at trial, and later recalled the police “only wrote down what we said that was bad for Roy.”
